Ignore Kate and her wardrobe for once, and focus instead on the impeccable tailoring of Prince William and other stylish British blokes, including the dashing Daniel Craig and Colin Firth. Do you need a queen’s ransom to achieve similar sartorial elegance? We asked two London-based experts for tips on buying wardrobe essentials to emulate these fashion-savvy Englishmen.

• Jeremy Langmead, editor in chief of the high-end men’s clothing site Mr. Porter, says, “The suit is Britain’s gift to the world, and despite the current emphasis on wearing separates, I think a man looks his best wearing one.” Note the nipped-in waist of the jacket and the slim trousers.

• Reed, of Charles Tyrwhitt, says, “A cut with more shape helps you look trimmer, even if you’re slightly overweight.” When selecting a shirt, wear a collar that suits the shape of your face, Reed says. A spread collar balances a thin face and long neck. Men with a rounder visage should choose a narrower, longer collar.
